The show centers on a bookstore manager, Joe Goldberg (Badgley), who meets a woman named Guinevere Beck (Lail) in his shop. Joe develops an obsession with Beck and begins to stalk her in full force. He memorizes her schedule, sneaks into her apartment, and kidnaps her on-again, off-again, aspiring-artisanal-soda-creator boyfriend.

And that's just the first episode. With a premise like that, you know "You" has to have some fun behind-the-scenes facts.

Here are some surprising things you might not have known about "You."

1/

The book's author has written for some shows you've probably watched.

The show is based on a book of the same name by Caroline Kepnes. "You" was Kepnes' first book, but according to her website, she's written for shows including "7th Heaven" and "The Secret Life of the American Teenager." Kepnes also wrote "You Got Me Babe," the eighth episode of "You."

Penn Badgley didn't want to play Joe at first.

At first, Badgley was reluctant to take on the role of Joe. In an interview with Entertainment Weekly, he said he was "conflicted" about the part, largely because the show is framed as a love story. "If this is a love story, what is it saying?" he said.

Ultimately, discussions with showrunners Sera Gamble and Greg Berlanti convinced Badgley the part and show had enough nuance to make it worth taking.

The facade of the bookstore where Joe works is a real store.

"You" used Logos Bookstore, a specialty bookstore on the Upper East Side of Manhattan, New York, as the exterior and front interior of Mooney's, according to Brick Underground. Although little was changed about the actual bookstore, Logos does not have a cage in its basement. The basement scenes in "You" were filmed on a separate set in the Bronx.

According to the American Booksellers Association, Logos is also featured in "Can You Ever Forgive Me?," a movie starring Melissa McCarthy as an out-of-work writer who begins forging old literary texts to make money.

The scene at the Greenpoint Avenue subway station likely wasn't filmed at the actual station.

The real-life Greenpoint, Brooklyn, subway stop is accented with green. In the show, the stop is accented with red.

The scene on what's alluded to as the Staten Island Ferry was likely not filmed on the Staten Island Ferry.

In episode eight, Beck asked Joe if he'd ever been to Staten Island. They go on to have a romantic ride on what is not actually the Staten Island Ferry, the only major way to travel by boat from Manhattan to Staten Island.

"What could happen on the upper deck of an immensely popular tourist destination?" Joe asked as he boarded what was supposedly the ferry.

The second season of "You" will take place in Los Angeles.

"You" has been renewed from a second season, which will air on Netflix instead of Lifetime. In an interview with TV Guide, Gamble confirmed that season two would be set in Los Angeles, where "Hidden Bodies," the book sequel to "You," is set.

But even if you've read the series, don't expect to know everything that's coming.

"Now the show has a life of its own and we are excited to take a few things in a direction that will be surprising to everyone, including fans of the books," Gamble said.

Candace (Ambyr Childers) wasn't always supposed to come back.

In the final scene of "You," Candace — Joe's subject of obsession before Beck who viewers were led to believe was dead — returns. This is a departure from the book, and one that wasn't initially going to happen in the TV show.

In an interview with Entertainment Weekly, Gamble said she and Berlanti decided at about the middle of the first season to bring Candace back, and they started to "misdirect" viewers to make them think she was dead.

9/

Peach Salinger got her name because author Caroline Kepnes thought it was "annoying."

Kepnes came up with the character of Joe while in a coffee shop.

"The voice clicked for me in that moment," she said. "I was obsessing about social media, and I had wanted to write something like this. But it was in that moment that I really got it. Joe is someone who is always the one looking and judging. He's very at ease with that in himself. That's where I found this great outlet for my little frustrations."
